Since a portion of the wall of thepot is immediately in contact with one'faice-of the gate, molten glass is prevented -.from passing and the wall of. the pot, and due to the wall or the pot being constructed. as shown in Figure 3, there is no chance forglass to flow into the air space 5',,-the outer wall of such space having an air vent 5*. Air under pressure is then allowed to enter the pot 2, creating pressure on the glass and thereby materiall aiding its-passage through the slots 8, such air passing through the pipe 6 into thepot. a It will be understood, hat the glass is'in' a slightly molten state so that when the two are provided which each side of the balan'ced gate 3 is then e between the gate the molten bers .10 by the air which enters the domes 5 under pressure.

It is, of course. to be understood, that the invention may be constructed in variousother manners and the parts associated in different relations, and therefore, ,I do not desire to be limited in any manner, except as set forth in the claims hereunto appended.
